I am passionate about preserving and sharing information about old
electronic and electro-mechanical calculators. I have run across some
interesting machines over the years, and figured I'd put information about
them up here for others to learn about and enjoy. If you have questions about
any of the machines listed here, or have more information or comments regarding
this site, please don't hesitate to drop me an EMail.

A listing of content of the museum by manufacturer is available
and can be seen by clicking HERE.

The machines are arranged in the list
in rough order as to their age (based on date of manufacture, not
introduction), oldest to newest. Click on any of the links in the
list below to learn more about each of the calculators in the museum.

Calculators listed that do not have a link associated with them do exist
in the museum's collection, but have not yet had exhibits prepared for them.

Many pages include a "Spec Sheet" for each machine.
The Spec Sheet includes a summary-style rundown of the
general information on the machine, such as size, weight, power requirements,
technology used, features, quirks, and more. Calculators with Spec Sheets will
have a Magenta-colored arrow in the list below. To see the Spec Sheet
for a machine, simply click on the main picture of the machine (or the
"Specs" link on the navigation bar at the top of the page) shown
at the top of each page. The Spec Sheet also has links back to the
main page for each machine, to related or similar machines, and back
to the main list of calculators in the museum.
